0.0.0.0 is not addressable, use 127.0.0.0 by default

The change is in hexojs/hexo-server, but this breaks the feature of allowing other machines to visit the site via hexo-server (which I think is good).
We have to change all the documents in hexojs/site to reflect this change.
Also add workaround (specifying the ip) to maintain current behavior.

See hexojs/hexo-server#14 and jekyll/jekyll#3048 for the discussion.

I find it better to merge hexojs/hexo-server#14 into master.

• As use hexo server bring more trouble likes 访问地址如果带参数返回的 Content-Type 有问题 #1149 but less benefits.
• Making hexo server a clearer position which differs from nginx or apache is better for the development of hexo-server.

And we should update docs of hexo-server to educate people not to use hexo-server for production.

I totally agree that hexojs/hexo-server#14 will be in, but not without or before the corresponding docs update.

Firstly, let's have a discussion in the society.
If dicided to do so, we can begin to do the work of docs, and I can do to zh-cn part.

BTW, ref: hexojs/site#133
If do it this, let's begin it from english version.

hexojs/hexo-server@4103a75 changed the display of hexo-server
We will stick with 0.0.0.0 as default.
